BUFFALO, N.Y. (AP) -- A New York Thruway spokesman says a malfunction at a western New York toll booth caused erroneous speeding citations for about 3,600 motorists with E-ZPass.

The errors happened at Exit 59, the Dunkirk-Fredonia exit, between May 28 and June 6.

In some cases, drivers received letters telling them their E-ZPass privileges had been temporarily suspended because they had gone through the toll booth at more than 40 mph.

The Thruway says new letters are going out explaining the mistake and advising that the violations will be overturned. Spokesman Dick Bennett says the speed-detecting equipment at the booth failed and has since been replaced.
